DIN-rail gateway for collecting Modbus data from RS485 / RS232 devices and sending it to MQTT, Modbus or OPC UA systems over Ethernet, optional 4G or Wi-Fi.
Appearance, connectors and included accessories follow the configuration confirmed in your quotation.
Ask for a sample or a small pilot. Availability, minimum quantity and sample charges depend on the selected model.
Price & delivery
Range, interface, accessories, quantity and destination affect the quote. Stock, lead time, freight, taxes and delivery terms need confirmation.
Warranty & support
Coverage, duration, exclusions and the fault-assessment process are confirmed for the quoted model before order.
Certificates & documents
Tell us the destination and required standard. We check the exact model, document revision and available evidence; a family listing is not certification.
Public documents describe this product family and selection options. Wiring, register maps and compliance documents must match the model and version selected for your order.

List every RS485 / RS232 device, register map, baud rate, parity setting and required refresh interval before choosing the serial-port count.
Use the 2-port version for up to 10 devices / 512 points or the 6-port version for up to 50 devices / 4,000 points, then verify the actual polling workload.
Choose Ethernet, 4G or Wi-Fi and define the required MQTT, Modbus TCP / RTU or OPC UA role. Protocol availability is model-dependent.
If network-outage recovery matters, decide whether a volatile supplier-format MQTT queue is sufficient. It does not survive power loss or restart and does not cover custom JSON, Sparkplug B or OPC UA history.

Write an acceptance test for timestamp handling, replay order and data completeness when delayed data affects billing, compliance or operations.
Confirm 9–36 VDC power, DIN-rail or wall space, antenna placement, IP30 suitability and destination-country certificates before release.
Compatible with
Modbus RTU devices using RS485 or RS232
Ethernet networks and optional 4G or Wi-Fi uplinks
MQTT brokers using the reviewed supplier-format template
Modbus TCP / RTU and OPC UA systems, subject to the selected model and protocol role
Typical package
Selected 2-port or 6-port gateway
9–36 VDC power, Ethernet patching and antenna accessories for 4G / Wi-Fi versions
Serial wiring plan and device register maps
MQTT topic, payload and security settings plus an outage-recovery acceptance test when buffering is required
Applications
I/O, protocol, antenna, power, enclosure and upstream platform are selected for the project.
Use this family when several Modbus devices need one DIN-rail gateway for Ethernet, optional 4G or Wi-Fi backhaul. It can collect serial data and hand it to MQTT, Modbus or OPC UA systems. The reviewed MQTT outage queue is useful for short network interruptions, but it is not nonvolatile storage.
Aggregate Modbus devices across 2 or 6 serial ports
Send field data over Ethernet, optional 4G or Wi-Fi
Publish selected values to MQTT or expose supported Modbus / OPC UA roles
Use the reviewed volatile MQTT queue for defined network-outage cases
It supports a reviewed MQTT outage queue for the supplier-format template. The queue can retain up to 100,000 data points while the network is unavailable, but it is RAM-based rather than nonvolatile storage.
Does queued data survive a power loss or restart?
No. Queued data is held in RAM and is lost if the gateway loses power or restarts. Use external nonvolatile logging or a different reviewed gateway when power-loss retention is required.
Which MQTT formats support outage replay?
The reviewed replay function is limited to the supplier-format MQTT template. Custom JSON and Sparkplug B do not use the same queue, and OPC UA does not provide equivalent historical replay.
Does replay preserve the original sampling timestamp?
That behavior has not been verified. Projects that depend on original timestamps, strict replay order or end-to-end completeness need a written acceptance test before purchase.
How do I choose between the 2-port and 6-port versions?
The 2-port version supports up to 10 devices and 512 points. The 6-port version supports up to 50 devices and 4,000 points. The final choice also depends on baud rates, register counts, polling interval, retries and whether devices need separate serial settings.
Does OPC UA provide historical replay?
No reviewed OPC UA historical replay is available for this family. OPC UA is provided as a server role on supported models; use the MQTT supplier-format queue or specify another logging path when historical recovery is required.
What should I provide when requesting a quote for the Edge IoT Gateway?
Connected devices, serial settings, register maps, point count and polling interval; Required 2-port or 6-port capacity and any need to separate different serial settings; Ethernet, 4G or Wi-Fi backhaul plus target country / mobile-network details; MQTT, Modbus or OPC UA role, broker / SCADA endpoint, payload and authentication
Where can I compare available model options?
Open the Industrial Monitoring Hardware Catalog linked on this page. Use it to compare equipment options before requesting a configuration.
Will it work with my existing system?
Compatibility is reviewed against your field signals, protocols and upstream platform. Typical pairings include Modbus RTU devices using RS485 or RS232, Ethernet networks and optional 4G or Wi-Fi uplinks, MQTT brokers using the reviewed supplier-format template.
